DETACHABLE HANDLE FOR HANDSAWS.

SPECIFICATION forming part of Letters Patent No. 785,459, dated March 21, 1905.

Application i'lled September 19, 1904. Serial No. 225,004.

To all whom it may concern:

Be it known that I, JOHN W EILER, a citizen of the United States of America, and a resident of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Detachable Handles for Handsaws, of which the following is a specification.

The present invention relates to handsaws, in which provision is made for a ready separation of the hand-grip from the saw-blade to permit of a compact storing of the parts in a carpenters tool-chest when not required for use; and the present improvement has for its object to provide a simple, strong, and convenient means for securing the hand-grip to the saw-blade in a rigid and substantial manner and which at the same time permits of a ready detachment between the parts when required, all as will hereinafter more fully appear and be more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation with parts in section of an ordinary handsaw to which the present invention is applied. Fig. 2 is a detail plan View ofthe same. Fig. 3 is a detail transverse section of the same at line m a', Fig. 1.

Similar numerals of'reference indicate like parts in the different views.

Referring to the drawings, 1 represents the hand-grip of the saw having the usual longitudinal groove or seat 2 for the reception of the butt of the saw-blade 3.

4 represents the usual transverse holdingpins arranged in separated relation and intersecting the groove or seat 2 to be engaged by the saw-blade, which blade in the present invention is formed with a pair of L-shaped slots 5, adapting the saw-blade for ready engagement with and detachment from the holding-pins 4 aforesaid.

6 is'a locking member having movement upon the hand-grip 1 in any usual manner and preferably by being pivotally connected thereto by means of a rearwardly-extending eye portion having` pivotal connection with a pair under face of the locking member 6, adapted for engagement with corresponding notches 9 in the back of the saw-blade, as shown, and when the saw-blade is in proper position in the hand-grip.

10 represents side plates at the respective sides of the locking member 6 to form a channel on the under side of the same to embrace the opposite sides of the hand-grip and at the same time afford a strong and substantial support for the ends of the transverse ribs 8, which in the present construction extend transversely from side plate to side plate and are integrally formed therewith.

11 is a keeper member secured to thehandgrip in adjacent relation to the forward end of the locking member 6 and formed with the keeper-eye 12 of the latch mechanism of the present improvement.

13 is a sliding latch-bolt moving in aguidehousing on the locking member 6 and adapted fordengagement with the keeper-eye 12 aforesai 1(14 is the guide-stem of the latch-bolt aforesai 15 is a coil-spring surrounding the guidestem 14, with a tendency to force the latchbolt forward.

16 is a thumb-piece secured to the latchbolt 13 for convenience in retracting said bolt in the operation of detaching the saw-blade from the hand-grip.

In the operation of the present invention the locking member 6 is iirst turned back from its engagement with the keeper member 11. rIhe saw-blade is then introduced into place and its L-shaped slots 5 made to engage with the transverse holding-pins 4. The locking member 6 is then brought down to engage its transverse teeth or ribs 8 with the notches 9 of the same blade and lock such saw-blade firmly in place. At the same time the latch-bolt 13 automatically engages tlie keeper-eye 12 to hold the aforesaid locking member 6 from accidental disengagement during the actual use of the saw.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A detachable saw-handle, comprising a IOO hand-grip provided with a longitudinal sawseat and with transverse holding-pins for detachable engagement with the saw-blade, a locking member pivotalllv attached at its rear end to the hand-grip and provided with transverse teeth or ribs intermediateV its length adapted to engage corresponding notches in the back of the saw-blade, and a spring-latch for securing said locking member in its engaged condition, substantially as set forth.

2. A detachable saw-handle, comprising a hand-grip provided with a longitudinal sawseat and with transverse holding-pins for detachable engagement with the saw-blade, a

locking member pivotally attached at its rear I5 end to the handgrip and provided with a channel on its under side and with transverse teeth or ribs in said channel adapted to engage corresponding notches in the back of the saw-blade, and a spring-latch for securing 20 said locking member in its engaged condition, substantially as set forth.

Signed at Chicago, Illinois, this 5th day of September, 1904.
